C#基于组件的开发实践

There are 3 separate implementations of MyCustomWebBrowser. The first one is in this folder. The other two were developed after the book went to print, and can be found on my website at http://www.faisoncomputing.com/samples/programming_samples.htm The three samples achieve the same goals, using different techniques. In all cases, the WebBrowser host is a Windows Form. The following list describes the implementation differences. 1. Book sample. This code uses a DLL that contains all the Ole interfaces necessary to customize the WebBrowser. The code shows how to implement the IDocHostUIHandler interface. 2. WebBrowserSample1, on my website, shows how to use the ICustomDoc interface to establish an IDocHostUIHandler for MsHtml. Using ICustomDoc to customize the WebBrowser is necessary when the host component doesn't implement IOleClientSite. 3. WebBrowserSample2, on my website, is the most complete example. It uses a Windows Form that implements the following Ole interfaces: IOleClientSite IDocHostUIHandler IOleDocumentSite IDocHostShowUI By virtue of being an OleClientSite, MsHtml automatically calls the IDocHostUIHandler and IDocHostShowUI methods of the host Windows Form. This example program has separate files for the following Ole interfaces used: IOleClientSite IDocHostUIHandler IOleDocumentSite IDocHostShowUI IOleClientSite IOleObject
